Learners estimate the volume for each of the nine simple figures shown. They then build it themselves with cubes and record the actual volume. Although this was designed as a homework assignment, most children do not have a set of unit cubes at home. With that in mind, consider this as an ideal in-class assignment for understanding the concept of volume for solid figures. For a real sweet treat, use sugar cubes as the unit cubes and have the class glue them in place to display for back to school night!
